3. Connection Diagram
<1> Remove the jumper when installing a DC reactor. Models CIMR-AC2A0110 through 2A0415 and 4A0058 through 4A1200 come with a built-in DC reactor.
<1> When installing a dynamic braking option, a thermal relay sequence should also be set up to shut off power to the drive in case overheat occurs.
<2> The drive’s protection function for the internal braking transistor needs to be disabled (L8-55 = 0) if using a regen unit such as a regen converter or
some type of dynamic braking options (and therefore not the internal braking transistor). If left enabled, a braking resistor fault (rF) may result. Make
sure Stall Prevention is disabled (L3-04 = 0) whenever using a regenerative converter, a regenerative unit or a dynamic braking option. If left
enabled, the drive may not stop within the specified deceleration time.
<3> Supplying power to the control circuit separately from the main circuit requires a 24 V power supply (option).
<4> This figure shows an example of a sequence input to S1 through S8 using a non-powered relay or an NPN transistor. Install the wire link between
terminals SC-SP for Sink mode and SC-SN for Source mode. Leave it out for external power supply. Never short terminals SP and SN as doing so
will damage the drive.
<5> The maximum current supplied by this voltage source is 150 mA if no digital input option card DI-A3 is used.
<6> The maximum output current capacity for the +V and -V terminals on the control circuit is 20 mA. Never short terminals +V, -V, and AC, as this can
cause erroneous operation or damage the drive.
<7> Set DIP switch S1 to select between a voltage or current input signal to terminal A2. The default setting is for current input.
<8> Set DIP switch S4 to select between analog or PTC input for terminal A3.
<9> Enable the termination resistor in the last drive in a MEMOBUS network by setting DIP switch S2 to the ON position.
<10> Use jumper S3 to select between Sink mode, Source mode or external power supply for the Safe Disable inputs.
<11> Disconnect the wire jumper between H1 - HC and H2 - HC when utilizing the Safe Disable input.
<12> Monitor outputs work with devices such as analog frequency meters, ammeters, voltmeters, and wattmeters. They are not intended for use as a
feedback-type of signal.
<13> Use jumper S5 to selection between voltage or current output signals at terminal AM and FM. Set parameters H4-07 and H4-08 accordingly
